Introduction
Thank you for choosing Harman Kardon!
With the purchase of a Harman Kardon
AVR 310 you are about to begin many years of
listening enjoyment. The AVR 310 has been
custom-designed to provide all the excitement
and detail of movie soundtracks and every
nuance of musical selections. With onboard
Dolby* Digital and DTS® decoding, the AVR 310
delivers six discrete channels of audio that take
advantage of the digital soundtracks from the
latest DVD and LD releases and Digital
Television broadcasts.
While complex digital systems are hard
at work within the AVR 310 to make all of this
happen, hookup and operation are simple.
Color-keyed connections, a programmable
remote control, and on-screen menus make the
AVR 310 easy to use. To obtain the maximum
enjoyment from your new receiver, we urge you
to take a few minutes to read through this
manual. This will ensure that connections to
speakers, source playback units and other
external devices are made properly. In addition,
a few minutes spent learning the functions of
the various controls will enable you to take
advantage of all the power the AVR 310 is
able to deliver.
If you have any questions about this product,
its installation or its operation, please contact
your retailer or custom installer. They are your
best local sources of information.
Description and Features
The AVR 310 is among the most versatile and
multi-featured A/V receivers available, incorporating a wide range of listening options. In
addition to Dolby Digital and DTS decoding for
digital sources, a broad choice of analog surround modes are available for use with sources
such as CD, VCR, TV broadcasts and the
AVR 310’s own FM/AM tuner. Along with Dolby
Pro Logic*,Dolby 3 Stereo and custom Hall and
Theater modes, only Harman Kardon receivers
offer Logic 7® to create a wider, more enveloping field environment and more defined flyovers and pans. Another Harman Kardon exclusive is VMAx®, which uses proprietary process-

ing to create an open, spacious sound field
even when only two front speakers are available. Finally, the AVR 310 is among the very
few A/V receivers that offer decoding of MP3
data, so that you may listen to the latest music
selections directly from compatible computers
or playback devices with the power and fidelity
you expect from Harman Kardon.
In addition to providing a wide range of listening options, the AVR 310 is easy to configure so
that it provides the best results with your
speakers and specific listening-room environment. On-screen menus make it simple to enter
settings for speakers, inputs and delay times,
while our exclusive EzSet™ remote measures a
system‘s sound levels and automatically calibrates them for perfectly balanced soundfield
presentation.

The AVR 310’s powerful amplifier uses
traditional Harman Kardon high-current design
technologies to meet the wide dynamic range
of any program selection.
Harman Kardon invented the high-fidelity
receiver more than forty-seven years ago. With
state-of-the-art circuitry and time-honored circuit designs, the AVR 310 is one of the finest
receivers ever offered by Harman Kardon.
■ Onboard Dolby Digital and DTS
Decoding Using Crystal® Chip
Technology
■ Harman Kardon’s Exclusive Logic 7 and
VMAx Modes
■ MP3 Decoding for Use with Computers
and Digital Audio Players
■

For the ultimate in flexibility, the AVR 310 features connections for four video devices, all
with both composite and S-Video inputs. Two
additional audio inputs are available, and a
total of six digital inputs make the AVR 310
capable of handling all the latest digital audio
sources. Coax and optical digital outputs are
available for direct connection to digital
recorders, and the front-panel coaxial jack may
be switched to an output for use with portable
recorders – a Harman Kardon exclusive. Two
video recording outputs, preamp outputs for
use with external power amplifiers, and a six
channel input make the AVR 310 virtually
future-proof, with everything needed to
accommodate tomorrow’s new formats right
on board.
The AVR 310’s flexibility and power extend
beyond your main home-theater or listening
room. The AVR 310 includes a sophisticated
multi-zone control system that allows you to
select one source for use in the main room and
a different one in a second room. Complete
control over volume is possible with a separate
infrared control link. To make it easy to operate
the AVR 310 from a remote room, a separate
“Zone II” remote is included.

Safety Information
Important Safety Information
Verify Line Voltage Before Use
Your AVR 310 has been designed for use with
120-volt AC current. Connection to a line voltage other than that for which it is intended
can create a safety and fire hazard and may
damage the unit.
If you have any questions about the voltage
requirements for your specific model, or about
the line voltage in your area, contact your selling
dealer before plugging the unit into a wall outlet.

Installation and Connections
System Installation
After unpacking the unit, and placing it on a solid
surface capable of supporting its weight, you will
need to make the connections to your audio and
video equipment.
Audio Equipment Connections
We recommend that you use high-quality interconnect cables when making connections to
source equipment and recorders to preserve the
integrity of the signals.
When making connections to audio source
equipment or speakers it is always a good practice to unplug the unit from the AC wall outlet.
This prevents any possibility of accidentally
sending audio or transient signals to the speakers that may damage them.
1. Connect the analog output of a CD player to
the CD inputs •.
NOTE: When the CD player has both fixed and
variable audio outputs it is best to use the fixed
output unless you find that the input to the
receiver is so low that the sound is noisy, or so
high that the signal is distorted.
2. Connect the analog Play/Out jacks of a cassette deck, MD, CD-R or other audio recorder to
the Tape Input jacks ¡. Connect the analog
Record/In jacks on the recorder to the Tape
Output jacks ™ on the AVR 310.
3. Connect the output of any digital sources
to the appropriate input connections on the
AVR 310 rear panel. Note that the Optical
and Coaxial digital inputs ij#% may
be used with a Dolby Digital or DTS source or
the output of a conventional CD or LD player’s
PCM (S/P-DIF) output.
4. Connect the Coaxial or Optical Digital
Outputs k on the rear panel of the AVR to the
matching digital input connections on a CD-R or
MiniDisc recorder.
5. Assemble the AM Loop Antenna supplied
with the unit as shown below. Connect it to the
AM and GND screw terminals ¢ .

6. Connect the supplied FM antenna to the FM
(75 ohm) connection ¶. The FM antenna may
be an external roof antenna, an inside powered
or wire lead antenna or a connection from a
cable TV system. Note that if the antenna or
connection uses 300-ohm twin-lead cable, you
must use the 300-ohm-to-75-ohm adapter supplied with the unit to make the connection.
7. Connect the front, center and surround
speaker outputs › ﬁ to the respective
speakers.
To assure that all the audio signals are carried
to your speakers without loss of clarity or resolution, we suggest that you use high-quality
speaker cable. Many brands of cable are available and the choice of cable may be influenced
by the distance between your speakers and the
receiver, the type of speakers you use, personal
preferences and other factors. Your dealer or
installer is a valuable resource to consult in
selecting the proper cable.
Regardless of the brand of cable selected, we
recommend that you use a cable constructed of
fine, multistrand copper with a gauge of 14 or
smaller. Remember that in specifying cable, the
lower the number, the thicker the cable.
Cable with a gauge of 16 may be used for short
runs of less than ten feet. We do not recommend that you use cables with an AWG equivalent of 18 or higher due to the power loss and
degradation in performance that will occur.
Cables that are run inside walls should have the
appropriate markings to indicate listing with UL,
CSA or other appropriate testing agency standards. Questions about running cables inside
walls should be referred to your installer or a
licensed electrical contractor who is familiar
with the NEC and/or the applicable local building codes in your area.
When connecting wires to the speakers, be certain to observe proper polarity. Remember to
connect the “negative” or “black” wire to the
same terminal on both the receiver and the
speaker. Similarly, the “positive” or “red” wire
should be connected to like terminals on the
AVR 310 and speaker.
NOTE: While most speaker manufacturers
adhere to an industry convention of using black
terminals for negative and red ones for positive,
some manufacturers may vary from this configuration. To assure proper phase and optimal

performance, consult the identification plate on
your speaker or the speaker’s manual to verify
polarity. If you do not know the polarity of your
speaker, ask your dealer for advice before proceeding, or consult the speaker’s manufacturer.
We also recommend that the length of cable
used to connect speaker pairs be identical.
For example, use the same length piece of
cable to connect the front-left and front-right
or surround-left and surround-right speakers,
even if the speakers are a different distance
from the AVR 310.
8. Connections to a subwoofer are normally
made via a line level audio connection from the
Subwoofer Output ¤ to the line-level input
of a subwoofer with a built-in amplifier. When a
passive subwoofer is used, the connection first
goes to a power amplifier, which will be connected to one or more subwoofer speakers. If
you are using a powered subwoofer that does
not have line-level input connections, follow the
instructions furnished with the speaker for connection information.
Video Equipment Connections
Video equipment is connected in the same manner as audio components. Again, the use of highquality interconnect cables is recommended to
preserve signal quality.
1. Connect a VCR’s or other video source’s
audio and video Play/Out jacks to the Video 1
or Video 2 In jacks £fh 32 on the rear
panel. The Audio and Video Record/In jacks on
the VCR should be connected to the Video 1
or Video 2 Out jacks ∞dg 33 on the
AVR 310.
2. Connect the analog audio and video outputs
of a satellite receiver, cable TV converter or
television set or any other video source to the
Video 3 e 31 jacks.
3. Connect the analog audio and video
outputs of a DVD or laser disc player to the
DVD jacks §c.
4. Connect the digital audio outputs of a DVD
player, satellite receiver, cable box or HDTV converter to the appropriate Optical or Coaxial
Digital Inputs ij#%.
5. Connect the Video Monitor Output ‹
jacks on the receiver to the composite or
S-Video input of your television monitor or
video projector.

15 INSTALLATION AND CONNECTIONS

Installation and Connections
Video Connection Note:
• Composite and S-Video signals may only be
viewed in their native formats. S-Video inputs
may only be viewed when the AVR 310 is
connected to a TV set or video display with
S-Video capability.

System and Power Connections
The AVR 310 is designed for flexible use with
multiroom systems, external control components and power amplifiers.
Main Room Remote Control Extension
If the receiver is placed behind a solid or
smoked glass cabinet door, the obstruction may
prevent the remote sensor from receiving commands. In this event, an optional remote sensor
may be used. Connect the output of the remote
sensor to the Remote IR Input jack a.
If other components are also prevented from
receiving remote commands, only one sensor is
needed. Simply use this unit’s sensor or a
remote eye by running a connection from the
Remote IR Output jack · to the Remote
IR Input jack on Harman Kardon or other compatible equipment.
Multiroom IR Link
The remote room IR receiver should be connected
to the AVR 310 via standard coaxial cable. Plug
the IR connection cable into the Multiroom IR
Input jack b on the AVR 310’s rear panel.
If other Harman Kardon compatible source
equipment is part of the main room installation,
the Remote IR Output jack · on the rear
panel should be connected to the IR IN jack on
source equipment. This will enable the remote
room location to control source equipment
functions.
NOTE: All remotely controlled components
must be linked together in a daisy chain.
Connect the IR OUT jack of one unit to the
IR IN of the next to establish this chain.
Multiroom Audio Connections
Depending on the distance from the AVR 310
to the remote room, two options are available
for audio connection:

16 INSTALLATION AND CONNECTIONS

Option 1: Use high-quality, shielded audio
interconnect cable from the AVR 310’s location
to the remote room. At the remote room, connect the interconnect cable to a stereo power
amplifier. The amplifier will be connected to the
room’s speakers. No volume control is required,
as the AVR 310 and the remote IR link will provide that function. At the AVR 310, plug the
audio interconnect cables into the MultiRoom Output jacks ‚ on the AVR 310’s
rear panel.
NOTE: The remote power amplifier must have
signal-sensing capability or be left on constantly to
assure automatic operation at the remote room.
Option 2: Place the amplifier that will provide
power to the remote location speakers in the
same room as the AVR 310, and connect the
Multiroom Output jacks ‚ on the rear
panel of the AVR 310 to the audio input of the
remote room amplifier. Use the appropriate
speaker wire to connect the optional power
amplifier to the remote speakers. High-quality
wire of at least AWG14 is recommended for
long multiroom connections.
IMPORTANT NOTE: Any cables run inside walls
should be CL3/FT4 rated, or carry any other certification that is required by the NEC or state and
local building and electrical codes. To avoid interference, audio and speaker cables should not be
parallel to, or run in the same conduits or path
with, AC cables. If you have any questions about
multiroom wiring, consult your dealer, custom
installer or low-voltage electrical contractor.
External Audio Power Amplifier
Connections
If desired, the AVR 310 may be connected to
optional, external audio power amplifiers.
When an external amplifier is used, connect the
Preamp Output jacks ⁄ to the inputs on the
external amplifier. Note that when external
amplifiers are used, the volume control is still
controlled by the AVR 310, although additional
volume controls on the external device may
impact the volume settings and output levels
from the AVR 310.

External Audio Decoder Connection
To provide for ultimate flexibility, the AVR 310
may be used in conjunction with optional,
external decoders for digital audio systems
other than the AVR 310’s own built-in Dolby
Digital and DTS decoding system or with DVD
players using the DVD Audio Format. If an
external decoder is used, connect the output
jacks of the decoder to the 6-Channel Direct
inputs ª, making sure to match channels.
These jacks may also be used for connections to
devices such as DVD players or High Definition
Television (HDTV) sets or decoders that feature
built-in digital surround decoders. Although the
digital decoding system in the AVR 310 will typically provide audio performance that is superior
to other decoders, you may use these jacks to
provide an additional 6-channel input for connection to a DVD player or HDTV set with a built-in
decoder and discrete 6-channel analog outputs.
AC Power Connections
This unit is equipped with two accessory AC
outlets. They may be used to power accessory
devices, but they should not be used with highcurrent draw equipment such as power amplifiers. The total power draw to each outlet may
not exceed 100 watts.
The Switched AC Accessory ﬂ outlet will
receive power only when the unit is on. This is
recommended for devices that have no power
switch or a mechanical power switch that may
be left in the “ON” position.
NOTE: Many audio and video products go into
a Standby mode when they are used with
switched outlets, and cannot be fully turned on
using the outlet alone without a remote control
command.
The Unswitched AC Accessory ‡ outlet will
receive power as long as the unit is plugged
into a powered AC outlet.
Finally, when all connections are complete, plug
the power cord into a nonswitched 110-volt AC
wall outlet. You’re almost ready to enjoy the
AVR 310!

System Configuration

Speaker Selection and Placement
The placement of speakers in a multichannel
home-theater system can have a noticeable
impact on the quality of sound reproduced.
No matter which type or brand of speakers is
used, the same model or brand of speaker
should be used for the front left, center and
front right speakers. This creates a seamless
front soundstage and eliminates the possibility
of distracting sonic disturbances that occur
when a sound moves across mismatched front
channel speakers.
Speaker Placement
Depending on the type of center channel
speaker in use and your viewing device, place
the center speaker either directly above or
below your TV, or in the center behind a perforated front projection screen.
Once the center channel speaker is installed,
position the left front and right front speakers
so that they are as far away from one another
as the center channel speaker is from the preferred listening position. Ideally, the front channel
speakers should be placed so that their tweeters
are no more than 24" above or below the
tweeter in the center channel speaker.
Depending on the specifics of your room
acoustics and the type of speakers in use, you
may find that imaging is improved by moving
the front left and front right speakers slightly
forward of the center channel speaker. If possible, adjust all front loudspeakers so that they
are aimed at ear height when you are seated
in the listening position.
Using these guidelines, you’ll find that it takes
some experimentation to find the correct location for the front speakers in your particular
installation. Don’t be afraid to move things
around until the system sounds correct. Optimize
your speakers so that audio transitions across
the front of the room sound smooth, and that
sounds from all speakers appear to arrive at the

listening position at the same time (without
delay from the center speaker compared to the
left and right speakers).
Surround speakers should be placed on the side
walls of the room, at or slightly behind the
listening position. The center of the speaker
should face into the room. The speakers should
be located so that the bottom of the cabinet
is at least two feet higher than the listeners’
ears when the listeners are seated in the
desired area.
If side-wall mounting is not practical, the
speakers may be placed on a rear wall, behind
the listening position. Again, they should be
located so that the bottom of the cabinet is at
least two feet higher than the listeners’ ears.
The speakers should be no more than six feet
behind the rear of the seating area.
Subwoofers produce nondirectional sound, so
they may be placed almost anywhere in a
room. Actual placement should be based on
room size and shape and the type of subwoofer
used. One method of finding the optimal location for a subwoofer is to begin by placing it in
the front of the room, about six inches from a
wall, or near the front corner of the room.
Another method is to temporarily place the
subwoofer at your normal listening position,
and then walk around the room until you find
a spot where the subwoofer sounds best. Place
the subwoofer in that spot. You should also
follow the instructions of the subwoofer’s manufacturer, or you may wish to experiment with
the best location for a subwoofer in your listening room.
System Setup
Once the speakers have been placed in the
room and connected, the remaining steps
in the setup process are to program the
AVR 310’s bass management system for the
type of speakers used in your system, calibrate
the output levels, and set the delay times used
by the surround sound processor.

17 SYSTEM CONFIGURATION

System Configuration
2. Press the Main Power Switch 1 in until
it latches and the word “OFF” on the top
of the switch disappears inside the front
panel. Note that the Power Indicator 3
will turn amber, indicating that the unit is
in the Standby mode.
3. Remove the protective plastic film from the
front-panel lens. If left in place, the film
may affect the performance of your remote
control.
4. Install the three supplied AAA batteries in
the remote as shown. Be certain to follow
the (+) and (–) polarity indicators that are
on the bottom of the battery compartment.

5. Turn the AVR 310 on either by pressing the
System Power Control 2 on the front
panel, or via the remote by pressing the
AVR Selector f or any of the Input
Selectors eg on the remote. The
Power Indicator 3 will turn green to
confirm that the unit is on, and the Main
Information Display Û will also light.
Using the On-Screen Display
When making the following adjustments, you
may find it easier to use the AVR 310’s onscreen display system. These easy-to-read displays give you a clear picture of the current status of the unit and make it easy to see which
speaker, delay, input or digital selection you are
making.
To view the on-screen menus, make certain you
have made a connection from the Video
Monitor Out jack ‹ on the rear panel to the
composite or S-Video input of your TV or projector. In order to view the AVR 310’s displays,
the correct video source must be selected on
the video display.
IMPORTANT NOTE: When viewing the displays
on a projection TV it is important that they not be
left on the screen for an extended period of time.
As with any video display, but particularly with
projectors, constant display of a static image such
as these menus or video game images may cause
the image to be permanently “burned into” the
CRT. This type of damage is not covered by the
AVR 310 warranty and may not be covered by
the projector TV set’s warranty.

18 SYSTEM CONFIGURATION

The AVR 310 has two on-screen display modes,
“Semi-OSD” and “Full-OSD.” When making
configuration adjustments, it is recommended
that the Full-OSD mode be used. This will place
a complete status report or option listing on
the screen, making it easier to view the available options. The Semi-OSD mode uses one-line
displays only.
Making Configuration Adjustments
The full OSD system is always available by
pressing the OSD button v. When this
button is pressed, the AUDIO SETUP
menu (Figure 1) will appear, and adjustments
are made from the individual menus. The semiOSD system is also available as a system
default, although it may be turned off by using
the ADVANCED SELECT menu. (See
page 32.) With the semi-OSD system, you may
make adjustments directly, by pressing the buttons on the front panel or remote control for
the specific parameter to be adjusted. For
example, press the Speaker Select button
32 ı to set the speaker configuration, etc.

Note that when the full OSD system is in use,
the menu selections are not shown in the Main
Information Display Û Y. When the full
OSD menu system is used, OSD ON will appear
in the Main Information Display Y and the
OSD Indicator M will illuminate to remind
you that a video display must be used. When
the semi-OSD system is used in conjunction
with the discrete configuration buttons, the onscreen display will show a single line of text
with the current menu selection. That selection
will also be shown in the Main Information
Display Y.
To use the full OSD menu system, press the
OSD button v. When the menu is on the
screen, press the ⁄/¤ buttons n until the
on-screen › cursor is next to the item you wish
to adjust, and then press the Set button p to
adjust that item. Note that the menus will
remain on the screen for 20 seconds, and then
they will “time-out” and disappear from the
screen. The time-out may be increased to as

much as 50 seconds by going to the
ADVANCED SELECT menu, and
changing the item titled FULL OSD
TIME OUT.
Setting the System Configuration
Memories
The AVR 310 features an advanced memory
system that enables you to establish different
configurations for the speaker configuration,
digital input, surround mode, delay times,
crossover frequency and output levels for each
input source. This flexibility enables you to
custom-tailor the way in which you listen to
each source and have the AVR 310 memorize
those settings. This means, for example, that
you may use different output levels or trims for
different sources, or set different speaker configurations with the resultant changes to the
bass management system. Once these settings
are made, they will automatically be recalled
whenever you select that input.
The factory default settings for the AVR 310,
have all inputs configured for an analog source,
stereo as the surround mode, the front left and
right speakers set to “large,” and a subwoofer
connected. Before using the unit, you will probably want to change the settings for most
inputs so that they are properly configured to
reflect the use of digital or analog inputs, the
type of speakers installed and the surround
mode specifics. Remember that since the
AVR 310 memorizes the settings for each input
individually, you will need to make these
adjustments for each input used. However, once
they are made, further adjustment is only
required when system components are
changed.
To make this process as quick and as easy as
possible, we suggest that you use the full-OSD
system with the on-screen menus, and step
through each input. Once you have completed
the settings for the first input, many settings
may be duplicated for the remaining inputs. It is
also a good idea to set the configuration data
in the order these items are listed in the
AUDIO SETUP menu, as some settings
require a specific entry in a prior menu item.
Remember that once the settings are made for
one input, they must be made for all other
input sources in your system.

System Configuration
Input Setup
The first step in configuring the AVR 310 is to
select an input. This may be done by pressing
the front panel Input Source Selector !
until the desired input’s name appears momentarily in the Main Information Display Y,
and the green LED lights next to the input’s
name in the front panel Input Indicators .
The input may also be selected by pressing
the appropriate Input Selector on the remote
control eg.
When using the full-OSD system to make the
setup adjustments, press the OSD button v
once so that the main AUDIO SETUP
menu (Figure 1) appears. Note that the › cursor will be next to the INPUT SETUP line.
Press the Set button p to enter the menu
and the IN/OUT SETUP menu (Figure 2)
will appear on the screen. Press the ‹/› buttons o 31 until the desired input name
appears in the highlighted video, as well as
being indicated in the front panel Input
Indicators  by the green LED next to the
desired input name. If the input will use the
standard left/right analog inputs, no further
adjustment is needed.

If you wish to associate one of the digital
inputs with the selected input source, press the
¤ button n on the remote while the
INPUT select menu (Figure 2) is on the
screen, and note that the on-screen cursor will
drop down to the DIGITAL IN line. Press
the ‹ / › buttons o 31 until the name of the
desired digital input appears. To return to the
analog input, press the buttons until the word
ANALOG appears. When the correct input
source appears, press the ¤ button n once
so that the › cursor appears next to
RETURN TO MENU, and press the Set
button p.
To change the digital input at any time using
the discrete function buttons and the semi-OSD
system, press the Digital Input Select button
Úq on the front panel or the remote.
Within five seconds, make your input selection

using the Selector buttons on the front panel
5 or the ⁄/¤ buttons n on the remote
until the desired digital or analog input is
shown in the Main Information Display Y
and in the lower third of the video display
connected to the AVR 310. Press the Set button p to enter the new digital input assignment.
An exclusive Harman Kardon feature is the ability to switch front panel jacks from their normal
use as inputs to output connections so that
portable recording devices may easily be connected. On the AVR 310, the Coaxial 3
Digital Jack % is normally an input, but it
may also be switched to a digital output for use
with CD-R/RW decks, MD recorders or other
digital audio recorders. To change the jack to
an output, press the ⁄/¤ buttons n while
the IN/OUT SETUP menu is on the
screen so that the › cursor is next to COAXIAL 3. Then press the ‹/› buttons o/ 31
so that the word OUT is highlighted. Note
that the Digital Coax 3 Status Indicator $
will turn red, indicating that the jack is now a
record output.

Logic 7 Music mode is a good choice for stereoonly source material.
NOTE: If you have selected Logic 7 C or M as
your surround mode for the current listening
session, and you are using a digital input, and
you have not changed the default surround
mode for that input source to the same Logic 7
mode, then you will notice that if the digital
signal is interrupted for any reason (such as
stopping the source device), upon resumption
of the signal, the AVR 310 will use a different
surround mode. In fact, the AVR 310 will use
whichever mode was set as the default for that
source. The factory default for all sources is
Stereo mode, unless the receiver detects a
Dolby Digital or DTS bitstream.
It is easiest to complete the surround setup
using the full-OSD on-screen menus. From the
AUDIO SETUP menu (Figure 1), press the
⁄/¤ buttons n until the › cursor is next to
the SURROUND SETUP menu. Press the
Set button p so that the SURROUND
SETUP menu (Figure 3 or 4) is on the screen.
*

SURROUND

SURROUND:

NOTE: A signal will be sent to this jack only
when the input selected for use by the AVR 310
is digital. Digital signals will be passed through
regardless of their format, and which digital
input (optical or coax) they are fed from.
However, analog signals are not converted to
digital, and the format of the signal (e.g., PCM,
Dolby Digital or DTS) may not be changed.
Selection of the Digital Coax 3 jack as an
output will remain effective as long as the
AVR 310 is on. However, once the unit is turned
off, the jack will revert to its normal use as an
input when the unit is turned on again.
Surround Setup
Once the basic input setup has been completed, the next step is to set the surround
mode you wish to use with an input. Since
surround modes are a matter of personal taste,
feel free to select any mode you wish – you
may change it later. However, to make it easier
to establish the initial parameters for the AVR
310, it is best to select Dolby Pro Logic for most
analog inputs and Dolby Digital for inputs connected to digital sources. In the case of inputs
such as a CD Player, Tape Deck or Tuner, you
may wish to set the mode to Stereo (as they are
not typically used with multichannel program
material), where it is unlikely that surroundencoded material will be used. Alternatively, the

Indicators ˜ on the front panel.

19 SYSTEM CONFIGURATION

System Configuration
Note that the data lines next to the items in the
screen display will show either numbers or a
series of dashes, depending on whether or not
the specific parameter is adjustable. For example, the Center Delay and Night Mode items are
only adjustable for Dolby Digital, and the Delay
Time is only adjusted for Dolby Digital and
Dolby Pro Logic. Note, also, that Dolby Digital
and DTS will only appear as choices (Figure 4)
when a digital input was previously selected.
Depending on the surround mode selected, you
will now proceed to change either the delay
time or the crossover frequency. For Dolby
Digital and Dolby Pro Logic, pressing the ⁄/¤
n buttons on the remote will take you to the
delay settings.
Delay Settings
If Dolby Digital or Dolby Pro Logic is selected as
the surround mode for an input, you may need
to adjust the delay time setting. Note that the
delay time is not adjustable for any other
modes.
Due to the different distances between the
listening position for the front channel speakers
and the surround speakers, the amount of time
it takes for sound to reach your ears from the
front versus surround speakers differs. You may
compensate for this difference through the use
of the delay settings to adjust the timing for
the specific speaker placement and acoustic
conditions in your listening room or home
theater.
The factory setting is appropriate for most
rooms, but some installations create an uncommon distance between the front and surround
speakers that may cause the arrival of front
channel sounds to become disconnected from
surround channel sounds.
To resynchronize the front and surround channels, follow these steps:
1. Measure the distance from the listening
position to the front speakers.
2. Measure the distance from the listening
position to the surround speakers.
3. Subtract the distance to the surround speakers from the distance to the front speakers.
a. When setting the delay time for the
Dolby Digital surround modes, the opti-

20 SYSTEM CONFIGURATION

mal delay time is the result of that subtraction. For example, if the front speakers are ten feet away and the surround
speakers are five feet away, the optimal
delay time is figured as 10–5=5. Thus, in
this example, the delay time for Dolby
Digital should be set at five milliseconds.
b. When setting the delay time for the Pro
Logic mode, take the result of the subtraction and add 15 to obtain the optimal delay time. For example, if the front
speakers are ten feet away and the surround speakers are five feet away, the
optimal delay time is figured as
10–5+15=20. Thus, in this example, the
Pro Logic delay should be set at twenty
milliseconds.

the ¤ button n and then the Set button
p to bring up the SURROUND SETUP
menu, and then press the ¤ button n once.
If the Dolby Digital mode is selected, the › cursor will stop at the CENTER DELAY line.
In that case, press the ‹ / › buttons o 31
until the number calculated using the formula
shown above appears in the display. When the
CENTER DELAY is entered, press the ¤
button n once to move to the next line.

NOTE: The DTS, Logic 7, Hall and Theater
modes use a fixed, nonadjustable delay time.

When the CENTER DELAY is set, or if the
Dolby Pro Logic mode is selected, the › cursor
will be at the SURR DELAY line so that
the delay for the surround speakers may be set.
Press the ‹ / › buttons o 31 until the number calculated using the formula shown above
appears in the display. When the delay settings
are complete, press the ¤ button n once to
move to the next line.

The Dolby Digital Mode also includes a separate setting for the center channel delay mode,
since the discrete nature of these signals makes
the location of the center channel speaker more
critical. To calculate the delay for the center
channel, measure the distance from the preferred listening position in the center of the
room to both the center channel speaker and
either the left or right speaker.

Note that the delay settings may also be
adjusted at any time when the Dolby Digital or
Dolby Pro Logic modes are in use by pressing
the Delay button on the front panel Ò or
remote 30 , followed by a press of the Set
button p. Next, press the ⁄/¤ buttons n
on the remote or the Selector buttons 5 on
the front panel until the desired figure appears
in the Main Information Display Y.

If the distances are equal, no further adjustment
is required and the center delay should be set to
zero. If the distance to the front speakers is
greater than the distance to the center speaker,
you may wish to reposition the speakers by
moving the front left and front right speakers
closer to the listening position or the center
speaker further away from the listening position.

Night Mode Settings
The Night mode is a feature of Dolby Digital
that uses special processing to preserve the
dynamic range and full intelligibility of a movie
sound track while reducing the peak level. This
prevents abruptly loud transitions from disturbing others, without reducing the sonic impact of
a digital source. Note that the Night mode is
only available when specially encoded Dolby
Digital signals are played.

If repositioning of the speakers is not possible,
adjust the center delay time, adding one millisecond of center channel delay for every foot
closer to the listening position the center
speaker is than the front speakers. For example,
if the front left and front right speakers are
each 10 feet from the listening position and the
center channel speaker is 8 feet away, the delay
is figured as 10–8=2, suggesting an optimal
center delay of 2 milliseconds.
To set the delay time for a specific input,
continue within the SURROUND SETUP
(Figure 4) menu. If the system is not already at
that point, press the OSD button v to bring
up the main AUDIO SETUP menu, press

To adjust the Night mode setting for an input
from the menu, make certain that the › cursor
is on the NIGHT line of the SURROUND
SETUP menu. Next, press ‹ / › buttons
o 31 to choose between the following
settings, as they appear in the on-screen
display:
OFF: When OFF is highlighted, the Night
mode will not function.
MID: When MID is highlighted, a mild compression will be applied.

System Configuration
MAX: When MAX is highlighted, a more
severe compression algorithm will be applied.
We recommend that you select the MID setting
as a starting point and change to the MAX
setting later, if desired.
Note that the Night mode may be adjusted
directly any time that a Dolby Digital source is
playing by pressing the Night button l.
When the button is pressed, the phrase
D-RANGE will appear in the lower third of
the video screen and in the Main Information
Display Y. Press the ⁄/¤ button n within
three seconds to select the desired setting.
When all settings for the surround setup have
been made, press the ⁄/¤ buttons n so that
the › cursor is next to RETURN TO
MENU, and press the Set button p to
return to the main menu.
Speaker Setup
This menu tells the AVR 310 which type of
speakers are in use. This is important as it
adjusts the settings that determine which
speakers receive low frequency (bass) information. For each of these settings use the
LARGE setting if the speakers for a
particular position are traditional full-range
loudspeakers that are capable of reproducing
sounds below 100Hz. Use the SMALL setting for smaller, frequency-limited satellite
speakers that do not reproduce sounds below
100Hz. Note that when “small” speakers are
used, a subwoofer is required to reproduce low
frequency sounds. Remember that the “large”
and “small” descriptions do not refer to the
actual physical size of the speakers, but to their
ability to reproduce low frequency sounds.
If you are in doubt as to which category
describes your speakers, consult the specifications in the speakers’ owner’s manual, or ask
your dealer.
It is easiest to enter the proper settings for the
speaker setup through the SPEAKER
SETUP menu (Figure 5). If that menu is not
already on your screen from the prior adjustments, press the OSD button v to bring up
the main AUDIO SETUP menu (Figure 1),
and then press the ¤ button n twice so that
the cursor is on the SPEAKER SETUP
line. At this point, press the Set button p to
bring up the SPEAKER SETUP menu
(Figure 5).

When the SPEAKER SETUP menu first
appears, the on-screen cursor › will be at the
top of the list of speaker positions, pointing
toward the LEFT/RIGHT line, which sets
the configuration for the front left and right
speakers. If you wish to make a change to the
front speakers configuration, press the ‹/› buttons o 31 so that either LARGE or
SMALL appears, matching the appropriate
description from the definitions shown above.
When SMALL is selected, low frequency
sounds will be sent only to the subwoofer output. Note that if you choose this option and
there is no subwoofer connected, you will not
hear any low frequency sounds from the front
channels.
When LARGE is selected, a full-range output
will be sent to the front left and front right
outputs. Depending on the choice made in
the SUBWOOFER line in this menu, bass
information may also be directed to the front
left/right speakers, a subwoofer or both.
When you have completed your selection for the
front channel, press the ¤ button n on the
remote to move the cursor to CENTER.
Press the ‹/› buttons o 31 on the remote
to select the option that best describes your
system based on the speaker definitions shown
below.
When SMALL is selected, low frequency
center channel sounds will be sent only to the
subwoofer output. Note that if you choose this
option and there is no subwoofer connected, you
will not hear any low frequency sounds from the
center channel speaker.

When NONE is selected, no signals will be
sent to the center channel output. The receiver
will operate in a “phantom” center channel
mode and center channel information will
be sent to the left and right front channel
outputs. When only front left and right speakers are used, with no center or surround speakers, VMAx is a good alternative mode.
When you have completed your selection for
the center channel, press the ¤ button n
on the remote to change the cursor to
SURROUND.
Press the ‹ / › buttons o 31 on the remote
to select the option that best describes the surround speakers in your system based on the
speaker definitions shown on this page.
When SMALL is selected, low frequency
surround channel sounds will be sent to the
subwoofer output only. Note that if you
choose this option and there is no subwoofer
connected, you will not hear any low frequency
sounds from the surround speakers.
When LARGE is selected, a full-range output
will be sent to the surround channel outputs,
and NO surround channel signals will be sent
to the subwoofer output.
When NONE is selected, surround sound
information will be split between the front-left
and front-right outputs. Note that for optimal
performance when no surround speakers are in
use, the Dolby 3 Stereo mode should be used
instead of Dolby Pro Logic.
When you have completed your selection for the
surround channel, press the ¤ button n on
the remote to move the cursor to SUBWOOFER.
Press the ‹ / › buttons o 31 on the remote
to select the option that best describes your
system.

When LARGE is selected, a full-range output
will be sent to the center speaker output, and
NO center channel signal will be sent to the
subwoofer output.

The choices available for the subwoofer position will depend on the settings for the other
speakers, particularly the front left/right positions.

NOTE: If you choose Logic 7 as the surround
mode for the particular input source for which
you are configuring your speakers, the AVR 310

If the front left/right speakers are set to
SMALL, the subwoofer will automatically be
set to SUB, which is the “on” position.

21 SYSTEM CONFIGURATION

System Configuration
If the front left/right speakers are set to
LARGE, three options are available:
• If no subwoofer is connected to the
AVR 310, press the ‹ / › buttons o 31
on the remote so that NONE appears in
the on-screen menu. When this option is
selected, all bass information will be routed
to the front left/right “main” speakers.
• If a subwoofer is connected to the AVR 310,
you have the option to have the front
left/right “main” speakers reproduce bass
frequencies at all times, and have the subwoofer operate only when the AVR 310 is
being used with a digital source that contains a dedicated Low Frequency Effects, or
LFE soundtrack. This allows you to use both
your main and subwoofer speakers to take
advantage of the special bass created for
certain movies, press ‹ / › buttons o 31
on the remote so that SUB (LFE) appears
in the on-screen menu.
• If a subwoofer is connected and you wish to
use it for bass reproduction in conjunction
with the main front left/right speakers,
regardless of the type of program source or
surround mode you are listening to, press
the ‹ / › buttons o 31 on the remote
so that SUB LFE+L/R appears in
the on-screen menu. When this option is
selected, a “complete” feed will be sent to
the front left/right “main” speakers, and the
subwoofer will receive the bass frequencies
under frequency selected in the next option
setting on this menu, as described below.
When you have completed your selection for
the subwoofer, press the ¤ button n on
the remote to change the cursor to
SUB X-OVER FREQ. The subwoofer
crossover setting may only be adjusted using
the on-screen display system.
At this line you will select the frequency at
which bass information is directed to the
Subwoofer Output ¤. The choices available
will depend on the setting made previously for
the front left/right speakers. When making
these selections, choose the crossover frequency
that is closest to that of your front left/right
speakers, or the upper frequency limit of your
subwoofer. This figure is normally printed in the
Owner’s Manual or data sheet for the speakers,
or consult the speaker’s manufacturer.
• When the front speakers have been set to
LARGE, the crossover choices are 40

crossover points of full range speakers.
Choose the option that is closest to your
speakers’ design.
• When the front speakers have been set to
SMALL, the crossover choices are 80
Hz or 100 Hz to match the typical
crossover points of the smaller speakers
used in satellite speaker systems. Choose
the option that is closest to your speakers’
design.

“small.” When the inner box and the two outer
boxes with circles inside them are lit, the
speaker is set for “large.” When no indicator
appears at a speaker location, that position is
set for “none” or “no” speaker.
NOTE: These icons are available only when
making setup changes in the semi-OSD mode.
As an example, in Figure 6 below, the left front
and right front speakers are set for “large,” the
center, left surround (LS) and right surround
(RS) speakers are set for small, and a subwoofer is set, as shown by the box with the
abbreviation “LFE”, which stands for “lowfrequency effects.”

The Speaker Configuration may also be
changed at any time without using the full-OSD
on-screen menu system by pressing the
Speaker Select button on the front panel ı
or remote 32 . Once the button is pressed,
FNT SPEAKER will appear in both the
lower third of the video display and the Main
Information Display Y.
Within three seconds, either press the front
panel ‹ / › Selector buttons 5 or the ⁄/¤
buttons n on the remote to select a different
speaker position, or press the Set button
Ôp to begin the adjustment process for the
front left and right speakers.
When the Set button Ôp has been pressed
and the system is ready for a change to the
speaker setting, the on-screen display and
Main Information Display Y will read
FNT LARGE or FNT SMALL, depending on the current setting. Press the front panel
‹ / › Selector Buttons 5 or the ⁄/¤ buttons
n on the remote until the desired setting is
shown, using the instructions for “large” or
“small” shown earlier.
If the configuration for another speaker position
needs to be changed, press the front panel ‹ / ›
Selector buttons 5 or the ⁄/¤ buttons n
on the remote to select a different speaker
position, and then press the front panel ‹ / ›
Selector buttons 5 or the ⁄/¤ buttons n
on the remote until the correct speaker setting
is shown.
To assist in making speaker configuration settings, the icons in the Speaker/Channel
Input Indicators Q change as the speaker
type is selected at each position. When only the
center icon box containing the abbreviation for
the speaker position is lit, the speaker is set for

Output Level Adjustment
Output level adjustment is a key part of the
configuration process for any surround sound
product. It is particularly important for a Dolby
Digital receiver such as the AVR 310, as
correct outputs will ensure that you hear
sound tracks with the proper directionality
and intensity.
IMPORTANT NOTE: Listeners are often
confused about the operation of the surround
channels. While some assume that sound
should always be coming from each speaker,
most of the time there will be little or no
sound in the surround channels. This is because
they are only used when a movie director or
sound mixer specifically places sound there to
create ambience, a special effect or to continue
action from the front of the room to the rear.
When the output levels are properly set it is
normal for surround speakers to operate only
occasionally. Artificially increasing the volume
to the rear speakers may destroy the illusion
of an enveloping sound field that duplicates
the way you hear sound in a movie theater or
concert hall.

System Configuration
Before beginning the output level adjustment
process, make certain that all speaker connections have been properly made. The system
volume should be set to the level that you will
use during a typical listening session. Finally,
make certain that the Balance Control * is
set to the center “12 o’clock” position.
Using EzSet
Harman Kardon’s exclusive EzSet remote makes
it possible to quickly and accurately set the
AVR 310’s output levels without the use of a
sound pressure meter, although manual adjustment is also available. However, for the easiest
set-up, follow these steps while seated in the
listening position that will be used most often:
1. Make certain that all speaker positions
have been properly configured for their
“large” or “small” settings (as outlined
above) and turn off the OSD system if it is
in use.
2. Adjust the volume so that it is at -15, as
shown in the on-screen display or Main
Information Display Y.
3. Hold the remote in front of you at arm’s
length, being sure not to cover the EzSet
Sensor Microphone 39 at the top of the
remote.
4. Press and hold the SPL Indicator Select
36 for three seconds. Release the button
when the Program/SPL Indicator c
stops flashing and you hear the test noise
from the front left speaker.
5. At this point, the EzSet circuitry will take
over, adjusting the output level of each
channel so that when the process is complete all levels will be equal and at the set
reference point. This process may take a
few minutes, depending on the extent of
adjustment required.
6. During the adjustment you will see the
location of the channel position being
adjusted appear in both the on-screen
display (if connected) and the Main
Information Display Y, alternating with
a readout of the output setting, relative to
the reference volume level. As the adjustment proceeds, a few things will happen
simultaneously:
• The channel position being adjusted will
flash in the Speaker/Channel Position
Indicators Q. If the test noise is heard
from a channel other than the one shown

in the Indicator, there is an error in the
speaker connections. If this is the case,
press the Test Button i TWICE to
stop the adjustment. Then, turn the unit
off and verify that all speakers are connected to the proper Outputs ›ﬁ.
• As each channel is set, the channel name
and the adjustment offset will appear in
the on-screen display (if connected) and
the Main Information Display Y.
While the level is changing, the
Program/SPL Indicator c will
change colors to reflect the output level
in relation to the reference. A red indication shows that the level is too high,
while an amber indication shows that the
level is too low. When the Indicator is
green, the level is correct, and the test
noise will move to the next channel.
• While adjustments are being made, the
red LED under the AVR Selector f
will flash. This is normal, and indicates
that EzSet is operating.
7. After the test noise has circulated once
through each channel, it will send the tone
to each channel once again, to verify the
settings.
8. After two complete circulations of the tone,
the levels are set. The Program Indicator
c will remain green at each channel.
Upon completion of the second circulation,
the Program/SPL Indicator will flash green
twice and then go out. The tone will stop
and the AVR 310 will return to normal
operation.
If you find that the output levels chosen by
EzSet are either uncomfortably low or high, you
may repeat the procedure. Return to Step 2
above and adjust the master volume either
slightly higher or lower to accommodate your
particular room layout and your tastes. You may
repeat this procedure as many times as necessary to achieve a desired result. In order to prevent possible damage to your hearing or your
equipment, we emphasize that you should
avoid setting the master volume above 0dB.
Manual Output Level Adjustment
Output levels may also be adjusted manually,
either to set them to a specific level with an
SPL meter, or to make fine tuning adjustments
to the levels obtained using the EzSet remote.

As soon as the new menu appears, you will
hear a test noise circulate from speaker to
speaker in a clockwise direction around the
room. The test noise will play for two seconds
in each speaker before circulating, and a blinking on-screen cursor will appear next to the
name of each speaker location when the sound
is at that speaker.
NOTE: Remember to verify that the speakers
have been properly connected. As the test noise
circulates, listen to make certain that the sound
comes from the speaker position shown in the
Main Information Display Y. If the sound
from a speaker location does NOT match the
position indicated in the display, turn the AVR
310 off using the Main Power Switch 1
and check the speaker wiring to make certain
that each speaker is connected to the correct
output terminal.
After checking for speaker placement, let the
test noise circulate again, and listen to see
which channels sound louder than the others.
Using the front left speaker as a reference,
press the ‹/› buttons o 31 on the remote
to bring all speakers to the same volume level.
Note that when one of the ‹/› buttons is
pushed, the test noise circulation will pause
on the channel being adjusted to give you time
to make the adjustment. When you release
the button, the circulation will resume after
five seconds.

Manual output level adjustment is most easily
done through the OUTPUT ADJUST
menu (Figure 7). If you are already at the main

23 SYSTEM CONFIGURATION

System Configuration
Continue to adjust the individual channels until
the volume level sounds the same from each
speaker. Note that adjustments should be made
with the ‹/› buttons o 31 on the remote
only, NOT the main volume controls. If you are
using a sound pressure level (SPL) meter for
precise level adjustment, set the volume so that
the meter reads 75dB, C-Weighting Slow.
You may also adjust the output levels manually
while using the level indication feature of the
EzSet remote. To activate the sensor and indicator, simply press and release the SPL Indicator
Select button 36 on the remote while the
test tone is circulating. The Program/SPL
Indicator c will change color to indicate the
level. Adjust the level using the ‹/› buttons
o 31 until the LED lights green for all channels. When it is red the level is too high; when
it is amber the level is too low. Press the SPL
Indicator Select 36 button when you are
finished to turn the sensor and Indicator off.
NOTE: The subwoofer output level is not
adjustable using the test tone. To change the
subwoofer level, follow the steps for Output
Level Trim Adjustment on page 30.
When all channels have an equal volume level,
the adjustment is complete. To exit this menu,
press the ⁄/¤ buttons n until the on-screen
› cursor is next to the RETURN TO
MENU line, and then press the Set button
p to return to the main AUDIO SETUP
menu.
The output levels may also be adjusted at any
time using the discrete buttons and semi-OSD
system. To adjust the output levels in this fashion, press the Test Tone Selector ˆi. As
soon as the button is pressed, the test tone will
begin to circulate as indicated earlier. The correct channel from which the test noise should
be heard will be shown in the lower third of
the video screen and in the Main
Information Display Y. While the test noise
is circulating, the proper channel position will
also be indicated in the Speaker/Channel
Indicators Q by a blinking letter within the
correct channel.

24 SYSTEM CONFIGURATION

To adjust the output level, press the Selector
buttons on the front panel 5 or the ‹/›
buttons o 31 until the desired level is
shown in the display or on screen. Once the
buttons are released, the test noise will begin
to circulate again in five seconds.
When all channels have the same output level,
press the Test Tone Selector ˆi button
again to complete the process.
NOTE: Output level adjustment is not available
for the VMAx or Surround Off mode.
Additional Input Adjustments
After one input has been adjusted for surround
mode, digital input (if any), speaker type, and
output levels, go back to the INPUT
SETUP line on the AUDIO SETUP
menu and enter the settings for each input that
you will use. In most cases, only the digital
input and surround mode will be different from
one input to the next, while the speaker type,
crossover frequency, night mode and output
level settings will usually be the same and may
be quickly entered by entering the same data
used for the original input.
Once the settings outlined on the previous
pages have been made, the AVR 310 is ready
for operation. While there are some additional
settings to be made, these are best done after
you have had an opportunity to listen to a variety of sources and different kinds of program
material. These advanced settings are described
on pages 27 to 31 of this manual. In addition,
any of the settings made in the initial configuration of the unit may be changed at any time.
As you add new or different sources or speakers, or if you wish to change a setting to better
reflect your listening taste, simply follow the
instructions for changing the settings for that
parameter as shown in this section.
Having completed the setup and configuration
process for your AVR 310, you are about
to experience the finest in music and hometheater listening. Enjoy!

Operation
Basic Operation
Once you have completed the setup and
configuration of the AVR 310, it is simple to
operate and enjoy. The following instructions
will help you maximize the enjoyment of your
new receiver:
Turning the AVR 310 On or Off
• When using the AVR 310 for the first time, you
must press the Main Power Switch 1 on the
front panel to turn the unit on. This places the
unit in a Standby mode, as indicated by the
amber color of the Power Indicator 3 . Once
the unit is in Standby, you may begin a listening
session by pressing the System Power Control
2 on the front panel or the AVR Selector
f. Note that the Power Indicator 3 will
turn green. This will turn the unit on and return it
to the input source that was last used. The unit
may also be turned on from Standby by pressing
any of the Input Selector buttons on the
remote efg∫ç∂ or the Source
button ! on the front panel.
NOTE: After pressing one of the Input Selector
buttons eg to turn the unit on, press the
AVR Selector f to set the remote control to
the AVR 310 functions.
To turn the unit off at the end of a listening
session, simply press the System Power
Control 2 on the front panel or the Power
Off button då on the remote. Power will
be shut off to any equipment plugged into the
rear panel Switched AC Outlets ﬂ and the
Power Indicator 3 will turn amber.
When the remote is used to turn the unit “off”
it is actually placing the system in a Standby
mode, as indicated by the amber color of the
Power Indicator 3.
• To program the AVR 310 for automatic turnoff, press the Sleep button j on the remote.
Each press of the button will increase the time
before shut down in the following sequence:

When the programmed sleep time has elapsed,
the unit will automatically turn off. Note that
the front panel display will dim to one half
brightness when the Sleep function is
programmed. To cancel the Sleep function,
press and hold the Sleep button j until
the information display returns to normal
brightness, the Sleep indicator numbers
disappear and the words SLEEP OFF
appear in the Main Information Display Y.
When you will be away from home for an
extended period of time it is always a good
idea to completely turn the unit off with the
front panel Main Power Switch 1.
NOTE: All preset memories are lost if the unit is
left turned off by using the Main Power
Switch 1 for more than two weeks.

Source Selection
• To select a source, press any of the Source
Selector buttons on the remote eg
ç∂.
• The input source may also be changed by
pressing the front-panel Input Source
Selector button !. Each press of the button
will move the input selection through the list of
available inputs.
• As the input is changed, the AVR 310 will
automatically switch to the digital input (if
selected), surround mode, speaker configuration, output levels, crossover frequency and
night mode status that were entered during the
configuration process for that source.
• The front-panel Video 4 Inputs ^ may be
used to connect a device such as a video game
or camcorder to your home entertainment
system on a temporary basis.
• As the input source is changed, the new input
name will appear momentarily as an on-screen
display in the lower third of the video display.
The input name will also appear in the Main
Information Display Y and a green LED will
light next to the selected input’s name in the
front-panel Input Indicators .
Video 1 and Video 2
• When an audio source is selected, the last
video input used remains routed to the Video

Outputs d and Video Monitor Output ‹.
This permits simultaneous viewing and
listening to different sources.
• When a Video source is selected, the video signal for that input will be routed to the Video
Monitor Output jack ‹ and will be viewable
on a TV monitor connected to the AVR 310.
Volume Control
• Adjust the volume to a comfortable level
using the front panel Volume Control Ó or
remote Volume Up/Down 34 I buttons.
• When listening in the Stereo mode, with the
surround circuits off, the Balance Control *
may be used to adjust the relative sound output
between the left front and right front speakers.
• To temporarily silence all speaker outputs
press the Mute button 38 K. This will interrupt the output to all speakers and the headphone jack, but it will not affect any recording
or dubbing that may be in progress. When the
system is muted, the MUTE indicator Z will
light in the Main Information Display Û.
Press the Mute button 38 K again to return
to normal operation.
• During a listening session you may wish to
adjust the Bass Control & and Treble
Control ( to suit your listening tastes or
room acoustics.
• To set the output of the AVR 310 so that
the output is “flat,” with the tone controls deactivated, press the Tone Mode button 6
button once or twice so that the words Tone
Out appear momentarily in the Main
Information Display Y. To return the tone
controls to an active condition, press the Tone
Mode 6 button once or twice so that the
words Tone In momentarily appear in the
Main Information Display Y.
• For private listening, plug the 1/4" stereo
phone plug from a pair of stereo headphones
into the front panel Headphone Jack 4.
Note that when the headphone’s plug is connected, the word HEADPHONE will scroll
once across the Main Information Display
Y and all speakers will be silenced. When the
headphone plug is removed, the audio feed to
the speakers will be restored.

Logic 7 M enhances the listening experience by presenting a wider front soundstage and greater
rear ambience. Both Logic 7 modes also direct low-frequency information to the subwoofer
(if installed and configured) to deliver maximum bass impact.

DOLBY 3 STEREO

Uses the information contained in a surround-encoded or two-channel stereo program to
create center-channel information. In addition, the information that is normally sent to the
rear-channel surround speakers is carefully mixed in with the front-left and front-right
channels for increased realism. Use this mode when you have a center-channel speaker
but no surround speakers.

No surround channels

THEATER

Surround processing uses matrix surround decoding to simulate a standard movie or
stage theater.

Delay time not adjustable

HALL 1
HALL 2

The two Hall modes offer two different matrix surround decoding choices that simulate
either a medium-sized chamber hall (Hall1) or a large concert hall or opera house (Hall 2)

Delay time not adjustable

VMAx Near
VMAx Far

When only the two front channel loudspeakers are used, Harman’s patented VMAx mode
delivers a three-dimensional sound space with the illusion of “phantom speakers” at the
center and surround positions. The VMAx N, or “Near Field” mode should be selected when
your listening position is less than five feet from the speakers. The VMAx F, or “Far Field” mode
should be selected when your listening positioin is greater than five feet from the speakers.

No surround channels

5-Channel Stereo

This mode takes advantage of multiple speakers to place a stereo signal at both the front and
back of a room. Ideal for playing music in situations such as a party, it places the same signal
at the front-left and surround-left, and front-right and surround-right speakers. The center
channel is fed a summed mono mix of the in-phase material of the left and right channels.

No delay is available for
this mode

SURROUND
OFF (STEREO)

This mode turns off all surround processing and presents the pure left- and rightchannel presentation of two-channel stereo programs.

Operation
Surround Mode Selection
One of the most important features of the
AVR 310 is its ability to reproduce a full
multichannel surround-sound field from digital
sources, analog matrix surround-encoded
programs and standard stereo programs. In all,
a total of thirteen listening modes are available
on the AVR 310.
Selection of a surround mode is based on personal taste, as well as the type of program
source material being used. For example, motion
pictures or TV programs bearing the logo of one
of the major surround-encoding processes, such
as Dolby Surround, DTS Stereo or UltraStereo††
may be played in either the Dolby Digital, Dolby
Pro Logic or Logic 7 Cinema surround modes
depending on the source material.
NOTE: Once a program has been encoded with
matrix surround information, it retains the surround information as long as the program is
broadcast in stereo. Thus, movies with surround
sound may be decoded via any of the analog
surround modes such as Pro Logic or Logic 7,
when they are broadcast via conventional TV stations, cable, pay TV and satellite transmission. In
addition, a growing number of made-for-television programs, sports broadcasts, radio dramas
and music CDs are also recorded in surround
sound. You may view a list of these programs
at the Dolby Laboratories Web site at
www.dolby.com.
Even when a program is not listed as carrying
intentional surround information, you may find
that the Pro Logic, Logic 7, VMAx and the Hall or
Theater modes often deliver enveloping surround
presentations through the use of the natural
information present in all stereo recordings.
However, for stereo, but not surround programs,
we suggest that you experiment with the other
modes.
Surround modes are selected using either the
front panel controls or the remote. To select a
surround mode from the front panel, press the
Surround Mode Selector 7 to scroll up or
down through the list of available modes. To
select a surround mode using the remote, press
the Surround Mode Selectork and then
press the ⁄ / ¤ buttons n to change the
mode. As you press the buttons, the Surround
mode name will appear in the Main
Information Display Y, and an individual
mode indicator will also light up CDFHI
JKLN. As the surround modes change, a

green LED will light next to the current mode in
the Surround Mode Indicators list ˜ on
the front panel.
Note that the Dolby Digital and DTS modes may
only be selected when a digital input is in use.
In addition, when a digital source is present,
the AVR 310 will automatically select and
switch to the correct mode (Dolby Digital or
DTS), regardless of the mode that has been previously selected. For more information on selecting digital sources, see the following section of
this manual.
To listen to a program in traditional two-channel
stereo, using the front-left and front-right
speakers only (plus the subwoofer if installed
and configured), follow the instructions shown
above for using the remote until SURR OFF
appears in the Main Information Display Y.

Digital Audio Playback
Digital audio is a major advancement over older
systems such as Dolby Pro Logic. It delivers five
discrete channels: left-front, center, right-front,
left-surround and right-surround. Each channel
reproduces full frequency range (20Hz to 20kHz)
and offers dramatically improved dynamic range
and significant improvements to signal-to-noise
ratios. In addition, digital systems have the capability to deliver an additional channel that is
specifically devoted to low-frequency information.
This is the “.1” channel referred to when you see
these systems described as “5.1”. The bass channel is separate from the other channels, but since
it is intentionally bandwidth-limited, sound
designers have given it that unique designation.
Dolby Digital
Dolby Digital (originally known as AC-3®) is
a standard part of DVD, and is available on
specially encoded LD discs and satellite broadcasts and it is a part of the new high-definition
television (HDTV) system.
Note that an optional, external RF demodulator
is required to use the AVR 310 to listen to the
Dolby Digital sound tracks available on laser
discs. Connect the RF output of the LD player to
the demodulator and then connect the digital
output of the demodulator to the the Optical
or Coaxial inputs ij#% of the AVR 310.
No demodulator is required for use with DVD
players or DTS-encoded laser discs.

DTS
DTS is another digital audio system that is
capable of delivering 5.1 audio. Although both
DTS and Dolby Digital are digital, they use different methods of encoding the signals, and
thus they require different decoding circuits to
convert the digital signals back to analog.
DTS-encoded sound tracks are available on
select DVD and LD discs, as well as on special
audio-only DTS discs. You may use any LD or
CD player equipped with a digital output to
play DTS-encoded discs with the AVR 310. All
that is required is to connect the player’s output
to either the Optical or Coaxial input on the
rear panel ij or front panel#%.
In order to listen to DVDs encoded with DTS
sound tracks, the DVD player must be compatible with the DTS signal as indicated by a DTS
logo on the player’s front panel. Note that early
DVD players may not be able to play DTSencoded DVDs. This does not indicate a problem with the AVR 310, as some players cannot
pass the DTS signal through to the digital outputs. If you are in doubt as to the capability of
your DVD player to handle DTS discs, consult
the player’s owner’s manual.

Selecting a Digital Source
To utilize either digital mode you must have
properly connected a digital source to the AVR
310. Connect the digital outputs from DVD
players, HDTV receivers, satellite systems or CD
players to the Optical or Coaxial inputs
ij#%. In order to provide a backup signal and a source for analog stereo recording,
the analog outputs provided on digital source
equipment should also be connected to their
appropriate inputs on the AVR 310 rear panel
(e.g., connect the analog stereo audio output
from a DVD to the DVD Audio inputs § on
the rear panel when you connect the source’s
digital outputs).
When playing a digital source such as DVD, first
select the input using the remote or front panel
controls as outlined in this manual. Next, select
the digital source by pressing the Digital
Input Selector button qÚ and then using
the ⁄/¤ buttons n on the remote or the
Selector buttons 5 on the front panel to
choose any of the OPTICAL or COAXIAL
inputs, as they appear in the Main
Information Display Y Display Indicator
BEor on-screen display. When the digital

27 OPERATION

Operation
source is playing, the AVR 310 will automatically detect whether it is a multichannel Dolby
Digital, DTS source, MP3 or a conventional
PCM signal, which is the standard output from
CD players. A Bitstream Indicator A will
light in the Main Information Display Û to
confirm that the digital signal is Dolby Digital,
DTS or PCM.

MP3: When the MP3 indicator lights, a compatible MPEG 1/Layer 3 digital signal is being
received. This is the popular audio format used
by many computer programs for recording compressed audio files. When an MP3 bitstream is
present, the sound will automatically be played
in the stereo (surround off) mode. The surround
modes are not available during MP3 playback.

Digital Status Indicators
When a digital source is playing, the AVR 310
senses the type of bitstream data that is present. Using this information, the correct surround mode will automatically be selected. For
example, DTS bitstreams will cause the unit to
switch to DTS decoding, and Dolby Digital bitstreams will enable Dolby Digital decoding.
When the unit senses PCM data from CDs and
LDs, it will allow the appropriate surround
sources to be selected manually. Since the
range of available surround modes is dependant on the type of digital data that is present,
the AVR 310 uses a variety of indicators to let
you know what type of signal is present. This
will help you to understand the choice of
modes.

In addition to the bitstream indicators, the
AVR 310 features a set of unique channel-input
indicators that tell you how many channels of
digital information are being received and/or if
the digital signal is interrupted.

When a digital source is playing, a Bitstream
Indicator A will light to show which type of
signal is playing:
DOLBY D: When the DOLBY D indicator
lights, a Dolby Digital bitstream is being
received. Depending on the settings on the
source player and specific surround information
and number of channels on the disc, a number
of surround modes are possible. For discs with
full 5.1 audio, only the Dolby Digital and VMAx
modes are available. When the Dolby Digital
signal is only two-channel, you may also select
from the Logic 7 Cinema/Music, Hall, Theater,
Dolby Pro Logic or Dolby 3 Stereo modes.
DTS: When the DTS indicator lights, a DTS
bitstream is being received. When the unit
senses this type of data, only the DTS mode
may be used.
PCM: When the PCM indicator lights, a standard Pulse Code Modulation, or PCM, signal is
being received. This is the type of digital audio
used by conventional compact disc and laser
disc recordings. When a PCM bitstream is present, all modes except Dolby Digital and DTS are
available.

28 OPERATION

These indicators are the L/C/R/LS/RS/LFE letters
that are inside the center boxes of the
Speaker/Channel Input Indicators Q in
the front panel Main Information Display
Û. When a standard analog signal is in use,
only the “L” and “R” indicators will light, as
analog signals have only left and right channels, respectively.
Digital signals, however, may have two, five or
six separate channels, depending on the program material, the method of transmission and
the way in which it was encoded. When a digital signal is playing, the letters in these indicators will light in response to the specific signal
being received. It is important to note that
although Dolby Digital, for example, is referred
to as a “5.1” system, not all Dolby Digital DVDs
or programs are encoded for 5.1. Thus, it is
sometimes normal for a DVD with a Dolby
Digital soundtrack to trigger only the “L” and
“R” indicators.
NOTE: Many DVD discs are recorded with both
“5.1” and “2.0” versions of the same soundtrack. When playing a DVD, always be certain to
check the type of material on the disc. Most
discs show this information in the form of a
listing or icon on the back of the disc jacket.
When a disc does offer multiple soundtrack
choices you may have to make some adjustments to your DVD player (usually with the
“Audio Select” button or in a menu screen
on the disc) to send a full 5.1 feed to the
AVR 310. It is also possible for the type of signal feed to change during the course of a DVD
playback. In some cases the previews of special
material will only be recorded in 2.0 audio,
while the main feature is available in 5.1 audio.
As long as your DVD player is set for 6-channel
output, the AVR 310 will automatically sense
changes to the bitstream and channel count
and reflect them in these indicators.

The letters used by the Speaker/Channel
Input Indicators Q also flash to indicate
when a bitstream has been interrupted. This
will happen when a digital input source is
selected before the playback starts, or when a
digital source such as a DVD is paused. The
flashing indicators remind you that the playback has stopped due to the absence of a
digital signal and not through any fault of the
AVR 310. This is normal, and the digital playback will resume once the playback is started
again.
Night Mode
A special feature of Dolby Digital is the Night
mode, which enables AC-3 input sources to be
played back with full digital intelligibilty while
reducing the minimum peak level by 1/4 to 1/3.
This prevents abruptly loud transitions from disturbing others, without reducing the impact of
the digital source. The Night mode is available
only when Dolby Digital signals with special
data are being played.
The Night mode may be engaged when a Dolby
Digital DVD is playing by pressing the Night
Mode Button l on the remote. Next, press
the ⁄/¤ buttons n to select either the middle range or full compression versions of the
Night mode. To turn the Night mode off, press
the ⁄/¤ buttons n until the message in the
lower third of the video display and the Main
Information Display Y reads D-Range
Off. When the Night mode is active, the
Night Mode Indicator O will also illuminate.
The Night mode may also be selected to always
be on at either level of compression using the
options in the Surround Setup Menu. See page
21 for information on using the menus to set
this option.
IMPORTANT NOTES ON
DIGITAL PLAYBACK:
1. When the digital playback source is stopped,
or in a pause, fast forward or chapter search
mode, the digital audio data will momentarily
stop, and the channel position letters inside the
Speaker/Channel Input Indicators Q will
flash. This is normal and does not indicate a
problem with either the AVR 310 or the source
machine. The AVR 310 will return to digital
playback as soon as the data is available and
when the machine is in a standard play mode.
2. Although the AVR 310 will decode virtually all
DVD movies, CDs and HDTV sources, it is possible

Operation
that some future digital sources may not be compatible with the AVR 310.
3. Note that not all digitally encoded programs
contain full 5.1-channel audio. Consult the program guide that accompanies the DVD or laser
disc to determine which type of audio has been
recorded on the disc. The AVR 310 will automatically sense the type of digital surround
encoding used and adjust to accommodate it.
4. When a digital source is playing, you may not
be able to select some of the analog surround
modes such as Dolby Pro Logic, Dolby 3, Stereo,
Hall, Theater or Logic 7.
5. When a Dolby Digital or DTS source is playing, it is not possible to make an analog recording using the Tape ™ and Video 1 or Video
2 Record Outputs ∞dg 33 . However, the
digital signals will be passed through to the
digital audio outputs k.
PCM Audio Playback
PCM (Pulse Code Modulation) is the noncompressed digital audio system used for
compact discs and laser discs. The digital circuits
in the AVR 310 are capable of high-quality
digital-to-analog decoding, and they may be
connected directly to the digital audio output
of your CD or LD player.
Connections may be made to either the rear
panel Optical or Coaxial inputs ij or the
front panel Digital Inputs #%.
To listen to a PCM digital source, first select the
input for the desired source (e.g., CD). Next press
the Digital Select button Ú q and then
use the ⁄ / ¤ buttons n on the remote, or the
Selector buttons 5 on the front panel, until
the desired choice appears in the Main
Information Display Y.
When a PCM source is playing, the PCM indicator A will light. During PCM playback you
may select any surround mode except Dolby
Digital or DTS.
Playback from PCM sources may also benefit
from the Logic 7 Mode. When playing back a
surround-encoded PCM source, such as an LD
or surround-encoded CD, use the Logic 7 C or
Cinema mode. When playing true stereo
recordings, use the Logic 7 M or Music mode
for a wider soundstage and increased rearchannel ambience.

NOTE: If you have selected Logic 7 C or M as
your surround mode for the current listening
session, and you are using a digital input, and
you have not changed the default surround
mode for that input source to the same Logic 7
mode, then you will notice that if the digital
signal is interrupted for any reason (such as
stopping the source device), upon resumption
of the signal, the AVR 310 will use a different
surround mode. In fact, the AVR 310 will use
whichever mode was set as the default for that
source. The factory default for all sources is
Stereo mode, unless the receiver detects a
Dolby Digital or DTS bitstream.
MP3 Audio Playback
The AVR 310 is one of the first A/V receivers to
provide on-board decoding for the MP3 audio
format used by computers and portable audio
devices. In addition, some new CD players are
capable of playing back optical discs that are
recorded with MP3, rather than standard CD
audio information. By offering MP3 decoding,
the AVR 310 is able to deliver more precise
conversion of the digital signals to an analog
output, along with the benefits of listening to
the MP3 audio through the AVR 310’s high
current amplifier and the speakers from your
surround system, rather than the smaller
speakers and low powered amplifiers typically
used with computers.
To take advantage of the AVR 310’s MP3 capabilities, simply connect the PCM output of a
computer’s sound card or the PCM output of a
portable digital audio device to either the rear
panel Digital Inputs ij or the front panel
Digital Inputs #%. As soon as the digital
signal is available, the MP3 Bitstream
Indicator A will light, and the audio will
begin playing.
NOTES:
• The AVR 310 is only capable of playing signals in the MP3 (MPEG 1/Layer 3) format. It
is not compatible with other computer audio
codecs.
• The digital audio input signal may be either
optical or coaxial, but the signal must be in
the PCM format. Direct connection of USB or
serial data outputs is not possible, even
though the signals are in the MP3 format. If
you have any questions about the data output format from your computer or a sound
card, check with the device’s Owner’s Manual
or contact the manufacturer’s technical support area.

Tuner Operation
The AVR 310’s tuner is capable of tuning AM,
FM and FM Stereo broadcast stations. Stations
may be tuned manually, or they may be stored
as favorite station presets and recalled from a
30-position memory.
Station Selection
1. Press the AM/FM Tuner Select button g
on the remote to select the tuner as an input.
The tuner may be selected from the front panel

Tape Recording
In normal operation, the audio or video source
selected for listening through the AVR 310 is
sent to the record outputs. This means that any
program you are watching or listening to may
be recorded simply by placing machines connected to the outputs for Tape Outputs ™ or
Video 1 or 2 Outputs ∞dg in the record
mode.
When a digital audio recorder is connected to
the Digital Audio Outputs k, you are able
to record the digital signal using a CD-R,
MiniDisc or other digital recording system.
In addition to the rear panel digital outputs, the
AVR 310 offers Harman Kardon’s exclusive con-

5. Press the Set button p to enter the
change.
6. Press the OSD button v to exit the menus
and return to normal operation.
Note that once the setting is made, the Digital
Coax 3 Status Indicator $ will turn red,
indicating that the Coaxial 3 Jack % is now
an output, instead of its default setting as an
input. Once the jack is changed to an output,
the setting will remain as long as the AVR 310
is turned on, unless the setting is changed in
the OSD menu system, as described above.
Note, however, that once the AVR 310 is turned
off, the setting is cancelled. When the unit is
turned on again, the Coaxial 3 Jack % will
return to its normal default setting as an input.
If you wish to use the jack as an output at a
future time, the setting must be changed again
using the OSD menu system.

Output Level Trim Adjustment
Normal output level adjustment for the
AVR 310 is established using the test tone, as
outlined on pages 22 and 23. In some cases,
however, it may be desirable to adjust the output levels using program material such as a test
disc, or a selection you are familiar with.
Additionally, the output level for the subwoofer
can only be adjusted using this procedure.
To adjust the output levels using program
material, first set the reference volume for the
front-left and front-right channels using the
Volume Control Ó 34 î.
If you are using a disc with test signals or an
external signal generator as the source from
which to trim the output levels, you may use
the EzSet feature of the remote to guide you to
the correct SPL level. To use the remote for this
purpose, press and quickly release the SPL
Indicator Select 36 to activate the sensor.
While the test tone is circulating, the Program
Indicator c will change color to indicate the
level. Adjust the level as shown above until the
LED lights green for all channels. When it is red
the level is too high; when it is amber the level
is too low. Press the SPL Indicator Select
36 to turn the sensor and indicator off.
Once the reference level has been set, press
the Channel Select button mÙ and note
that FRONT L LEV will appear in the
Main Information Display Y. To change
the level, first press the Set button pÔ ,
and then use the Selector buttons 5 or the
⁄ / ¤ buttons n to raise or lower the level.
DO NOT use the volume control, as this will
alter the reference setting.

NOTES:
• The digital outputs are active only when a
digital signal is present, and they do not
convert an analog input to a digital signal,
or change the format of the digital signal.
In addition, the digital recorder must be
compatible with the output signal. For
example, the PCM digital input from a CD
player may be recorded on a CD-R or
MiniDisc, but Dolby Digital or DTS signals
may not.

Once the change has been made, press the Set
button pÔ and then press the Selector
buttons 5 or the ⁄/¤ buttons n to select
the next output channel location that you wish
to adjust. To adjust the subwoofer level, press
the Selector buttons 5 or the ⁄/¤ buttons
n until WOOFER LEV appears in the
Main Information Display Y or on-screen
display.

• Please make certain that you are aware of
any copyright restrictions on any material you
copy. Unauthorized duplication of copyrighted
materials is prohibited by federal law.

Press the Set button pÔ when the name of
the desired channel appears in the Main
Information Display Y and on-screen display, and follow the instructions shown earlier
to adjust the level.

Advanced Features
The AVR 310 is equipped with a number of
advanced features that add extra flexibility to
the unit’s operation. While it is not necessary
to use these features to operate the unit, they
provide additional options that you may wish
to use.
Display Brightness
The AVR 310’s Main Information Display
Û is set at a default brightness level that is

v to exit the menu system.
Turn-On Volume Level
As is the case with most audio/video receivers,
when the AVR 310 is turned on, it will always
return to the volume setting in effect when the
unit was turned off. However, you may prefer to
always have the AVR 310 turn on at a specific
setting, regardless of what was last in use
when the unit was turned off. To change the
default condition so that the same volume level
is always used at turn-on, you will need to
make an adjustment in the ADVANCED
SELECT menu. To start the adjustment,
press the OSD button v to bring the main
AUDIO SETUP menu (Figure 1) to the
screen. Press the ¤ button n six times,
until the on-screen › cursor is next to the
ADVANCED line. Press the Set button p

press the ¤ button n once so that the onscreen › cursor is next to the DEFAULT
VOL SET line. To set the desired turn-on
volume, press the ‹ / › buttons o 31 until
the desired volume level is shown on the
DEFAULT VOL SET line. Note that this
setting may NOT be made with the regular volume controls.
NOTE: Since the setting for the turn-on volume
cannot be heard while the setting is being
made, you may wish to determine the setting
before making the adjustment. To do this, listen
to any source and adjust the volume to the
desired level using the regular volume controls

Ó 34 î. When the desired volume level to
be used at turn-on is reached, make a note of
the setting as it appears in the lower third of
the video screen or in the Main Information
Display Y. (A typical volume level will appear
as a negative number such as –25dB.) When
making the adjustment, use the ‹/› buttons
o 31 to enter this setting.
Unlike some of the other adjustments in this
menu, the turn-on volume default will remain in
effect until it is changed or turned off in this
menu, even when the unit is turned off.
If you wish to make other adjustments, press
the ⁄/¤ Buttons n until the on-screen ›
cursor is next to the desired setting or the
RETURN TO MAIN MENU line and
press the Set button p. If you have no other
adjustments to make, press the OSD button
v to exit the menu system.
Semi-OSD Settings
The semi-OSD system places one line messages
at the lower third of the video display screen
whenever the Volume, Input Source, Surround
mode or tuner frequency of any of the configuration settings are changed. The semi-OSD system is helpful in that enables you to have feedback on any control changes or remote commands using the video display when it is difficult to view the front-panel displays. However,
you may occasionally prefer to turn these displays off for a particular listening session. You
may also want to adjust the length of time the
displays remain on the screen. Both of those
options are possible with the AVR 310.
To turn off the semi-OSD system, you will need
to make an adjustment in the ADVANCED
SELECT menu (Figure 9). To start the
adjustment, press the OSD button v to bring
the main AUDIO SETUP menu to the
screen. Press the ¤ Button n six times, until
the on-screen ¤ cursor is next to the
ADVANCED line. Press the Set Button p
to enter the ADVANCED SELECT menu.
At the ADVANCED SELECT menu make
certain that the on-screen › cursor is next to
the SEMI OSD DEFAULT line by pressing the ⁄/¤ buttons n as needed. Next,
press the › Button 31 so that the word
OFF is highlighted in the video display.
Note that this setting is temporary and will
remain active only until it is changed or until
the AVR 310 is turned off. Once the unit is

turned off, the semi-OSD displays will remain
activated, even if they were switched off for the
previous listening session.
To change the length of time that the semi-OSD
displays remain on the screen, go to the
ADVANCED SELECT Menu as outlined
earlier, and press the ⁄/¤ buttons n as
needed, until the on-screen › cursor is next to
the SEMI-OSD TIME OUT line. Next,
press the ‹ / › Buttons o 31 until the

Full-OSD Time Out Adjustment
The FULL-OSD menu system is used to
simplify the setup and adjustment of the
AVR 310 using a series of on-screen menus. The
factory default setting for these menus leaves
them on the screen for 20 seconds after a
period of inactivity before they disappear from
the screen or Time Out. This Time Out is a safety
measure to prevent image retention of the
menu text in your monitor or projector, which
might happen if they were left on indefinitely.
However, some viewers may prefer a slightly
longer or shorter period before the Time Out
display.
To change the Full-OSD Time Out, you will need
to make an adjustment in the ADVANCED
SELECT menu (Figure 9). To start the
adjustment, press the OSD button v to bring
the main AUDIO SETUP menu to the

Multiroom Operation
The AVR 310 is fully equipped to operate
as the control center for a multiroom system
with optional remote external Infrared (IR) sensors, speakers and power amplifiers. Although
some multi- room installations will require the
services of a specially trained installer, it is possible for the average do-it-yourself hobbyist to
install a simple remote room system.
Installation
The key to remote room operation is to link the
remote room to the AVR 310’s location with
wire for an infrared link and speakers or an
amplifier. For installation instructions for
Multiroom use, see page 16.

Multiroom Setup
Once the audio and IR link connections have
been made, the AVR 310 needs to be configured
for multiroom operation using the steps below.
Press the OSD button v to bring the main

As long as an IR feed to the AVR 310 has been
established from the remote room, using any of
the buttons on either remote will control the
remote location volume 34 î, change the
tuner frequency uç, change the tuner
preset `© or mute the output 38 ˚.
If the Remote IR Output jack ° on the
AVR 310 is connected to an IR Input jack on
compatible Harman Kardon audio components
such as CD, DVD or cassette players, the transport functions of those machines may also be
controlled using the Transport Controls
xÉƒ©˙∆ on either remote
control.
To turn the system off from the remote room,
press the Power-Off button då.
Remember that the AVR 310 may be turned on
or off from the remote room regardless of the
system’s operation or status in the main room.
NOTE: When the tuner is selected as the source
for the remote zone, any change to the frequency or preset will also change the station
being listened to in the main room, if the tuner
is in use there. Similarly, if someone in the main
room changes the station, the change will also
impact the remote room.
To activate the feed to the remote room, while
you are in the main listening room where the
AVR 310 is located, press the Multiroom but-

ton 33 on the remote. Next, press the Set
button p. Press the ⁄ / ¤ buttons n to
turn the multiroom feed on or off. When the
multiroom system is on, the Multi indicator P
will light in the Main Information Display
Û, and the Main Information Display Y
or OSD will display MULTI ON. Press the
Set button p to enter the setting.
When the multiroom system is turned on, the
input selected using the Multi Room menu will
be fed to the Multiroom Output jacks ‚ on
the rear panel. The volume will be as set in the
previous selection, although it may also be
adjusted using an optional IR sensor and the
Zone II remote in the remote location or on the
optional audio power amplifier connected to the
Multiroom Output jacks ‚.
Once the multiroom system is turned on, it will
remain on even if the AVR 310 is placed in the
Standby mode in the main room by pressing
the Power Off button å or the System

Even when the AVR 310 is turned off in the
main room, the multiroom system may be
turned on at any time by pressing the
Multiroom button 33 , or any of the
Selector buttons ∫ç∂ in the remote
room.

Programming the Remote
The AVR 310 is equipped with a powerful
remote control that will control not only the
receiver’s functions, but also most popular
brands of audio and video equipment, including
CD players, cassette decks, TV sets, cable boxes,
VCRs, satellite receivers and other home-theater
equipment. Once the AVR 310’s remote is programmed with the codes for the products you
own, it is possible to eliminate most other
remotes and replace them with the convenience
of a single, backlit universal remote control.

Programming the Remote
As shipped from the factory, the remote is fully
programmed for all AVR 310 functions, as well
as those of most Harman Kardon CD changers,
DVD players, CD players and cassette decks. In
addition, by following one of the methods below,
you may program the remote to operate a wide
range of devices from other manufacturers.
Direct Code Entry
This method is the easiest way to program your
remote to work with different products.
1. Use the tables in the following pages to
determine the three-digit code or codes that
match both the product type (e.g., VCR, TV),
and the specific brand name. If there is
more than one number for a brand, make
note of the different choices.
2. Turn on the unit you wish to program into
the AVR 310 remote.
3. Press and hold both the Input Selector
e for the product you wish to control
(e.g., VCR, TV) and the Mute button 38
at the same time.When the Program/SPL
Indicator c turns amber and begins
flashing, release the buttons. It is important
that you begin the next step within 20 seconds.

Input Selector will flash three times
before going dark to confirm the entry.
6. Try all of the functions on the remote to
make certain that the product operates
properly. Keep in mind that many manufacturers use a number of different combinations of codes, so it is a good idea to make
certain that not only the Power control, but
the volume, channel and transport controls
work as they should. If functions do not
work properly, you may need to use a different remote code.
7. If a code cannot be entered to turn the
unit off, if the code for your product does
not appear in the tables in this manual, or
if not all functions operate properly, try
programming the remote with the Auto
Search Method.
Auto Search Method
If the unit you wish to include in the AVR 310’s
remote is not listed in the code tables in this
manual or if the code does not seem to operate
properly, you may wish to program the correct
code using the Auto Search method that follows:
1. Turn on the unit that you wish to include in
the AVR 310 remote.
2. Press the Input Selector e for the type
of product to be entered (e.g., VCR, TV) and
the Mute button 38 at the same time.
Hold both buttons until the red light under
the Input Selector e stays lit. Note that
the next step must take place while the red
light is on, and it must begin within 20 seconds after the light illuminates.
3. Point the AVR 310 remote towards the
unit to be programmed, and press either ⁄
or ¤ button $. Each press will send out a
series of codes from the remote’s built-in
database. When the unit being programmed
turns off, release ⁄ /¤ button $, as that
is your indication that the correct code is
in use.

4. Point the AVR 310’s remote towards the unit
to be programmed, and enter the first threedigit code number using the Numeric Keys
buttons r. If the unit turns off, the correct
code has been entered. Press the Input
Selector e again, and note that the red
light will flash three times before going dark
to confirm the entry.

4. Press the Input Selector e, and note
that the red light under the Input Selector
will flash three times before going dark to
confirm the entry.

5. If the device to be programmed in does NOT
turn off, continue to enter three-digit code
numbers until the equipment turns off. At
this point, the correct code has been
entered. Press the Input Selector e
again and note that the red light under the

5. Try all of the functions on the remote to
make certain that the product operates.
Keep in mind that many manufacturers use
a number of different combinations of
codes, and it is a good idea to make certain
that not only the Power control works, but

also that the volume, channel and transport
controls, as appropriate. If all functions do
not work properly, you may need to AutoSearch for a different code, or enter a code
via the Direct Code Entry method.
Code Readout
When the code has been entered using the Auto
Search method, it is always a good idea to find
out the exact code so that it may be easily reentered if necessary. You may also read the codes
to verify which device has been programmed to
a specific Control Selector button.
1. Press and hold both the Input Selector
e for the device you wish to find the
code for and the Mute button 38 at the
same time. Note that the Program/SPL
Indicator c will initally turn amber.
Release the buttons and begin the next
step within 20 seconds.
2. Press the Set button p. The Program/SPL
Indicator c will then blink green in a
sequence that corresponds to the three-digit
code, with a one-second pause between each
digit. Count the number of blinks between
each pause to determine the digit of the
code. One blink is the number 1, two blinks is
the number 2, and so forth. Ten blinks are
used to indicate a “0.”
Example: One blink, followed by a one-second
pause, followed by six blinks, followed by a
one-second pause, followed by ten blinks indicates that the code has been set to 160.

35 PROGRAMMING THE REMOTE

Programming the Remote
Learning Codes
In addition to using codes from the remote’s
internal code library, the AVR 310’s remote is
able to “learn”codes from remotes that may
not be in the code library. In addition, you may
use this function to “learn over” the codes from
a preprogrammed device to add functions not
included in the preprogrammed codes. To learn
or transfer codes from an IR remote to the
AVR 310’s remote, follow these steps:
1. Place the front of the original remote with
the code being sent so that it is facing the
IR Transmitter Window b on the
AVR 310 remote “head-to-head.” The
remotes should be between one and three
inches apart.
2. Select the button on the remote that you
wish to use as the device selector for the
codes about to be entered. This may be any
of the Input Selectors e.

8. Repeat Steps 1 through 7 for any additional remotes you wish to “teach” into the
AVR 310 Remote.
Erasing Learned Codes
The AVR 310’s remote allows you to remove or
erase, the code learned into a single button for a
single device, to remove or erase the code set for
all the codes that have been programmed into
specific device buttons, or to erase all commands
that have been learned to all devices.
To erase a single learned code from within a single device’s settings, follow these steps:
1. Press and hold both the Input Selector

Program/SPL Indicator c will blink green
two times and then return to amber.

5. Within five seconds, press and hold the button on the original remote that you wish to
“teach” into the AVR 310 remote. When the
Program/SPL Indicator c turns green
three times, release the button. Note that the
Program Indicator will then begin to flash
amber again.

6. To erase other buttons within the same device,
press them as noted in Step 5.

NOTE: If the Program/SPL Indicator c
turns red during Step 5 or 6, the programming was not successful. Repeat the steps to
see if the code will “take.”
6. Repeat Steps 4 though 6 for each button on
the source remote that you wish to transfer
to the AVR 310 remote.
7. Once all codes have been transferred from
the original source remote to the AVR 310
remote, press the Learn button h.

indicate that the codes have been erased.
Macro Programming
Macros enable you to easily repeat frequently
used combinations of commands with the press
of a single button on the AVR 310’s remote control. Once programmed, a macro will send out
up to 19 different remote codes in a pre-determined sequential order enabling you to automate the process of turning on your system,
changing devices, or other common tasks. The
AVR’s remote can store up to five separate
macro command sequences, one that is
associated with the Power On button a, and
four more that are accessed by pressing the
Macro buttons w.
1. Press the Mute button 38 and the

2. Note that the Program/SPL Indicator c
will flash amber, and the LED under the AVR
Selector f will turn red.
3. Within ten seconds, press the Surround
Mode Selector/Channel Down
button k.

Programmed Device Functions
Once the AVR 310’s remote has been programmed for the codes of other devices, press
the appropriate Input Selector e to change
the remote from controlling the AVR 310 to controlling the additional product. When you press
any one of the selectors, it will briefly flash in red
to indicate that you have changed the device
being controlled.
When operating a device other than the
AVR 310, the controls may not correspond
exactly to the function printed on the remote
or button. Some commands, such as the volume
control, are the same as they are with the
AVR 310. Other buttons will change their
function so that they correspond to a secondary
label on the remote. For example, the Sleep
and Surround mode selector buttons also function as the Channel Up and Channel Down
buttons when operating most TV sets, VCRs or
cable boxes. The Channel Up/Down indication is
printed directly on the remote. For many standard CD players, cassette decks, VCRs and DVD
functions, the standard function icons are printed
on top of the buttons.
For some products, however, the function of a
particular button does not follow the command
printed on the remote. In order to see which
function a button controls, consult the Function
List tables printed on page 40. To use those
tables, first check the type of device being controlled (e.g., TV, VCR). Next, look at the remote
control diagram pictured at the left. Note that
each button has a number on it.
To find out what function a particular button
has for a specific device, find the button number
on the Function List and then look in the
column for the device you are controlling. For
example, button number 54 is the Macro 2
button for the AVR 310, but it is the “Favorite”
button for many cable television boxes and
satellite receivers. Button number 32 is the
Delay button for the AVR 310, but the + Time
button for CD players.

37 PROGRAMMING THE REMOTE

manual to describe the button functions for the
AVR 310.
Notes on Using the AVR 310 Remote With
Other Devices.
• Manufacturers may use different code sets for
the same product category. For that reason, it
is important that you check to see if the code
set you have entered operates as many controls as possible. If it appears that only a few
functions operate, check to see if another code
set will work with more buttons.
• When a button is pressed on the AVR 310
remote, the red light under the Input
Selector e for the product being operated
should flash briefly. If the Device Control
Selector flashes for some but not all buttons
for a particular product, it does NOT indicate a
problem with the remote but rather that no
function is programmed for the button being
pushed.

Volume Punch-Through
The AVR 310’s remote may be programmed to
operate the Volume Control 34 and Mute
38 functions of either the TV or the AVR 310 in
conjunction with any of the devices controlled by
the remote. For example, since the AVR 310 will
likely be used as the sound system for TV viewing, you may wish to have the AVR 310’s volume
activated, although the remote is set to run the
TV. Either the AVR 310 or TV volume control may
be associated with any of the remote’s devices.
To program the remote for Volume PunchThrough, follow these steps:
1. Press the Input Selector e for the unit you
wish to have associated with the volume control and the Mute button 38 at the same
time until the red light illuminates under the
Input Selector e and note that the
Program/SPL Indicator c will flash amber.
2. Press the Volume Up button 34 and note
that.the Program/SPL Indicator c will
stop flashing and stay amber.
3. Press either the AVR Selector f or the
Input Selector e, depending on which
system’s volume control you wish to have
attached for the punch-through mode. The

38 PROGRAMMING THE REMOTE

Program/SPL Indicator c will blink green
three times and then go out to confirm the
data entry.
Example: To have the AVR’s volume control
activated even though the remote is set to
control the TV, first press the Video/TV
Input Selector e and the Mute button
38 at the same time. Next, press the
Volume Up button 34 , followed by the
AVR Input Selector f.
NOTE: Should you wish to return the remote to
the original configuration after entering a Volume
Punch-Through, you will need to repeat the steps
shown above. However, press the same Input
Selector in Steps 1 and 3.

Channel Control Punch-Through
The AVR 310’s remote may be programmed to
operate so that the channel control function for
either the TV, cable or satellite receiver used in
your system may be used in conjunction with one
of the other devices controlled by the remote. For
example, while using and controlling the VCR, you
may wish to change channels on a cable box or
satellite receiver without having to change the
device selected by the AVR 310 or the remote. To
program the remote for Channel Control PunchThrough, follow these steps:
1. Press the Input Selector button e for the
device you wish to have the channel control
associated with and the Mute button 38 at
the same time until the red light illuminates
under the Input Selector e and the
Program/SPL Indicator c flashes amber.
2. Press the Volume Down button 34 . The
Program/SPL Indicator c will stop flashing and stay amber.
3. Press and release the Input Selector button
e for the device that will be used to change
the channels. The Program/SPL Indicator
c will blink green three times and then go
out to confirm the data entry.
Example: To control the channels using your
Cable Box or Satellite Receiver while the
remote is set to control the VCR, first press the
VID 1/VCR Input Selector button e and
the Mute button 38 at the same time. Next,
release them and press the Volume Down
button 34 , followed by the VID 2/TV Input
Selector button e.

NOTE: To remove the Channel Control PunchThrough and return the remote to its original configuration, repeat the steps shown in the example
above. However, press the VID 1/VCR Input
Selector in Steps 1 and 3.

Transport Control Punch-Through
The AVR 310’s remote may be programmed to
operate so that the Transport Control Functions
x (Play, Stop, Fast Forward, Rewind, Pause and
Record) for a VCR, DVD or CD will operate in conjunction with one of the other devices controlled
by the remote. For example, while using and controlling the TV, you may wish to start or stop your
VCR or DVD without having to change the device
selected by the AVR 310 or the remote. To program the remote for Transport Control PunchThrough, follow these steps:
1. Press the Input Selector e for the device
you wish to have the channel control associated with and the Mute button 38 at the
same time until the red light illuminates, under
the Input Selector e and the Program/
SPL Indicator c flashes amber.
2. Press the Play button x. The Program/SPL
Indicator c will stop flashing and stay
amber.
3. Press and release the Input Selector button
e for the device that will be used to change
the channels. The Program/SPL Indicator
c will blink green three times and then go
out to confirm the data entry.
Example: To control the transport of a DVD
player while the remote is set to control the TV,
first press the VID 2/TV Input Selector button eand the Mute button 38 at the
same time. Next, release them and press the
Play button x, followed by the DVD Input
Selector button e.
NOTE: To remove the Channel Control PunchThrough and return the remote to its original configuration, repeat the steps shown in the example
above. However, press the VID 2/TV Input
Selector in Steps 1 and 3.
NOTE: Before programming the remote for
Volume, Channel or Transport Punch-Through,
make certain that any programming needed for
the specific TV, CD, DVD, Cable or Satellite
Receivers has been completed.

Programming the Remote
Reassigning Device Control
Selectors
Although each Input Selector e is normally
assigned to the category of product shown on the
remote, it is possible to reassign one of these buttons to operate a second device of another type.
For example, if you have two VCRs but no satellite
receiver, you may program the “SAT” button to
operate a second VCR. Before following the normal programming steps for either Three-Digit entry
or Auto Search code entry, you must first reassign
the button with the following steps:
1. Press the Input Selector e you wish to
reassign and the Mute button 38 at the
same time until the red light illuminates under
the Input Selector e and the Program/
SPL Indicator c flashes amber.

1. Press any of the Input Selector buttons e
and the ”O“ button r at the same time
until the Program/SPL Indicator c begins
to flash amber.
2. Press the ”3“ button r three times.
3. The red LED under the Input Selector e will
go out and the Program/SPL Indicator c
will stop flashing and turn green.
4. The Program/SPL Indicator c will remain
green until the remote is reset. Note that this
may take a while, depending on how many
commands are in the memory and need to be
erased.
5. When the Program/SPL Indicator c goes
out, the remote has been reset to the factory
settings.

2. Press the Input Selector e for the device
you wish to program into the reassigned
button.
3. Enter the three-digit code for the specific
model you wish the reassigned button to
operate.
4. Press the same Input Selector e pressed in
Step 1 once again to store the selection. The
red LED under the re-assigned Input Selector
will flash three times and then go out.
Example: To use the CBL/SAT button to operate a second VCR, first press the CBL/SAT
Input Selector e and the Mute button
38 at the same time until the red light glows
under the CBL/SAT e button. Press the VCR
e button, followed by the three-digit code
for the specific model you wish to control.
Finally, press the CBL/SAT e button again.

Resetting the Remote Memory
As you add components to your home-theater system, occasionally you may wish to totally reprogram the remote control without the confusion of
any commands, macros or ”Punch-Through“ programming that you may have done. To do this, it is
possible to reset the remote to the original factory
defaults and command codes by following these
steps. Note, however, that once the remote is
reset, all commands or codes that you have
entered will be erased and will need to be reentered:

delay times and speaker configuration data,
first put the unit in Standby by pressing the
System Power Control button 2. Next,
press and hold the Tone Mode 6 and the
FM Mode Selector @ buttons for three
seconds.

To correct this problem, first unplug the unit
from the AC wall outlet and wait at least three
minutes. After the pause, reconnect the AC
power cord and check the unit’s operation. If
the system still malfunctions, a system reset
may clear the problem.

The unit will turn on automatically and display
the RESET message in the Main
Information Display Y. Note that once you
have cleared the memory in this manner, it is
necessary to re-establish all system configuration
settings and tuner presets.

input assignments as well as the tuner presets.
After a reset the unit will be returned to the
factory presets, and all settings for these items
must be reentered.
If the system is still operating incorrectly, there
may have been an electronic discharge or
severe AC line interference that has corrupted
the memory or microprocessor.
If these steps do not solve the problem, consult
an authorized Harman Kardon service depot.
